The Caribbean Sea

High pressure across the NE Atlantic extends W-SW across the central Atlantic and weakly north of the NE Caribbean. The associated pressure gradient is producing moderate to fresh tradewinds across the basin. Generally fair weather prevails across most of the basin under the stable influence of an upper level trough. Widely scattered moderate convection is seen across the coastal waters of Cuba, north of 20N, due to associated moisture from a shearline extending from the central Bahamas across central Cuba to the Yucatan Channel.

The monsoon trough extends from Colombia near 11N73W, through Panama and into the eastern Pacific Ocean. Scattered strong convection across NW Colombia extends across the SW Caribbean to 11.5N79W.

The weak high pressure ridge extending north of the NE Caribbean will maintain moderate to fresh tradewinds across the basin through Wed. Trade winds will increase basin wide Wed night through Fri night as high pressure builds across the western Atlantic. Expect fresh to strong easterly winds in the Gulf of Honduras mainly at night through Thu night.
